Question
In the 1.0 M CuSO4 solution, the following species are present: Cu2+, SO42-, H2O, H3O+, and OH-. Based on the observed changes that occurred in each electrode, write the RHR, OHR, and the balanced overall reaction of the electrolytic cell. The reactions should be consistent with the observations.
